Emergency managers directed Oʻahu residents in "red zones" to head inland on Tuesday as the state faced a tsunami. But Oʻahu's evacuation maps also show yellow "Extreme Tsunami" zones. Did people in those areas need to evacuate as well?

When a Tsunami Advisory is issued, there will be no coastal evacuations; however officials will evacuate the ocean and beaches. Stay out of the ocean and away from beaches, and stay out of any canals or streams that feed directly from the ocean.

The Pacific Tsunami Warning Center’s latest tsunami warning update for Hawaii says that first waves to hit Kauai measured at amplitude 3 to 4 feet in Hanalei, and 0.7 to 0.8 feet Nawiliwili. Tsunami amplitude is “measured relative to normal sea level,” according to the 8 p.m. update.
